empty 'Set-Cookie' header bug

[moumar]

camping generate an empty 'Set-Cookie' header that lead to output too much "\r\n" when calling Controller#to_s.

This is ok when dealing with plain text (like HTML) output, but is problematic when generating binary content (like on-the-fly generated images), leading to corrupt files.

Here a patch
